Problems solved by technology
[0021] Meanwhile, in such a conventional electromagnetic switch device, there is a disadvantage in that it is difficult to separate the relay 20 from the junction box 10 without providing the remover 30.
As a result, the relay 20 may move on the junction box 10 so that poor contact may occur between the relay 20 and the junction box 10, and because the pair of hook protrusions 24 are not securely caught by the pair of hook grooves 14, The relay 20 may also be inadvertently separated from the junction box 10

Embodiment Construction
[0053] Hereinafter, preferred embodiments of an electromagnetic switch device according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0054] Such as Figure 4 to Figure 9As shown, the electromagnetic switchgear according to the embodiment of the present invention may include: a junction box 100, which has an accommodating space formed by a side plate 130 and a bottom plate 120; and a relay 200, which has a housing 210 A fixed contact (not shown) and a movable contact (not shown) which are in contact with or separated from each other, and the relay 200 is configured to be installed to the accommodation space 110 or separated from the accommodation space 110 .
[0055] The junction box 100 may be configured such that the receiving space 110 corresponds to the shape of the housing 210 .
[0056] In this case, the housing 210 is formed in a rectangle and the accommodation space 110 may also be formed in a ...

Disclosed is an electromagnetic switching device, including: a junction box having an accommodating space formed to be one side open by side plates and a bottom plate; and a relay having fixed contacts and movable contacts within an casing and detachable to and / or from the accommodating space, wherein the junction box includes a pair of protrusions which are protruded from the side plates to an opposite side to the accommodating space; wherein the relay includes a lever which is hinge-coupled to the casing and caught by the pair of protrusions; and wherein the lever is configured to press the relay toward the bottom plate when rotating in one direction, and to press the relay toward a direction to become distant from the bottom plate when rotating in opposite direction, thereby enabling the relay to be easily detachable from the junction box.
Description
technical field [0001] The present invention relates to an electromagnetic switchgear, and more particularly, to an electromagnetic switchgear in which a relay is detachably mounted in a junction box. Background technique [0002] As well known in the art, an electromagnetic switching device is an electrical contact type disconnecting device configured to supply or cut off electric power, and may be used in various industrial appliances, machines, vehicles, and the like. [0003] figure 1 is a perspective view showing a conventional electromagnetic switch device and a remover, figure 2 is showing figure 1 The perspective view of the relay, and image 3 is to show that the figure 1 A cross-sectional view of the state where the remover is inserted between the junction box and the relay. [0004] refer to Figure 1 to Figure 3 , a conventional electromagnetic switching device includes: a junction box 10; and a relay 20 disposed in the junction box 10 and configured to br...
